The Mongols, added to Civilization III in Play the World, have the Keshik as their unique unit. They replace the Knight, which is obtained through Chivalry. They cost 60 shields. Their attack/defense/movement ratio is 4/2/2, which is a downgrade because the Knight's ratio is 4/3/2. Unlike the Knight, however, Keshiks do not require Iron in their strategic resource box to create; they only need Horses.
